against the bill of lading to be sure all crates and cartons have been
received. Before accepting delivery, carefully inspect each carton or
crate for visible shipping damage. If any damage is noticed, the carrier
should make the proper notation on the delivery receipt acknowledging
the damage. Make notations of all damage on all copies of the bill of
lading and have all copies countersigned by the delivering carrier. The
carrier should also fill out a Carrier Inspection Report. File claim for
damage with the carrier. Physical damage to the unit after acceptance is
not the responsibility of Fantech.
Unpack each carton or crate and verify that all required parts and proper
quantities of each item have been received. Refer to drawings for part
descriptions. Report shortages or missing items to your local
representative to arrange for replacement parts.
Due to availability of carriers and truck space, it is not possible to
guarantee that all items will be shipped together. Verification of
shipments must be limited to only those items on the bill of lading.
The unit nameplate must be checked to make sure the voltage agrees
with the power supply available.

General Installation
CAUTION: Sheet metal parts, screws, clips and similar items
inherently have sharp edges, and it is necessary that the
installer and service personnel exercise caution.
The installation of this equipment shall be in accordance with the
regulations of authorities having jurisdiction and all applicable codes.
This equipment is to be installed by an experienced installation company
and fully trained personnel.
The mechanical installation of the exhaust ventilator consists of making
final connections between the unit and building services, duct
connections.
When motors and drive packs are shipped in separate cartons from the
fan, check the carton labels to make sure the motor and drive pack you
received are the correct combination for the fan being purchased. Refer
to the fan components list included in these instructions.
Motor and Drive Pack Installation
Before mounting the motor to the fan motor/bearing support plate check
the nameplate voltage of the motor to insure that it is compatible with the
supply voltage. If the motor is a dual or tri voltage make sure the
connections inside the motor are properly wired to match the supply
voltage. Refer to the wiring schematic on the motor nameplate or inside
the junction box. Record the motor that was installed and the voltage that
the fan is wired for on the fan nameplate by checking the appropriate
boxes.
Mount the motor to the fan in a slot pattern on the motor/bearing support
plate that matches the motor frame footprint. The motor is mounted on
the same side of the motor/bearing support plate as the bearings and fan
shaft. The motor is usually mounted to the right side of the fan shaft. Use
the hardware provided which is located in the motor compartment of the
fan. Loosely snug the bolts at this time. Sizes 15, 16 and 18 have a
spacer bolt pack included. The junction box on certain motors will hit the
shaft. Use the spacers to raise the motor junction box above the shaft.
Install the adjustable sheave onto the motor shaft and the fixed sheave
onto the fan shaft. Align the sheaves as shown on page 5 of these
instructions and torque the set screws from 70 to 87 in-lbs. Install the
V-belt around the sheaves and slide the motor in the slots provided to
tension the belt (see page 4 for procedure). Once the belt is properly
tensioned and the alignment is correct tighten down the motor mounting
bolts.
Electrical Connection
1. Connect supply wiring to the disconnect switch (if supplied). Check the
wiring diagrams on the motor for connections.
2. The motor is factory set at the voltage marked on the fan nameplate.
Check the line voltage with the nameplate voltage and wiring
diagrams.
3. The main power wiring should be sized for the amperage shown on
the nameplate. Size wires in accordance with the ampacity tables in
Article 310 of the National Electrical Code. If long wires are required,
it may be necessary to increase wire size to prevent excessive
voltage drop. Wires should be sized for a max of 3% voltage drop.
CAUTION: Use copper conductors only.
CAUTION: Protect wiring from sharp edges. Leave some slack
in the line to prevent damage.
4. Disconnect switches (if supplied) are not fused. The power leads must
be protected at the point of distribution in accordance with the fan
nameplate.
5. On fans without a thermal protector integral to the motor (refer to
unit or motor nameplate to determine if protector is present) a
separate overload device is required. Refer to Sections 430-32 of the
N.E.C. for sizing.
6. All units must be electrically grounded in accordance with local codes
or, in the absence of local codes, with the latest edition of the
National Electrical Code (ANSI/NFPA 70). A ground lug is provided as
standard in the unit terminal box. Size grounding conductor in
accordance with Table 250-95 of the National Electrical Code. DO
NOT use the ground lug for connecting a neutral conductor.
7. Supply voltage to the power ventilator should not vary by more than
10% of the value indicated on the unit nameplate. Phase unbalance
must not exceed 2%.
WARNING: Failure of motor due to operation on improper line
voltage or with excessive phase unbalance constitutes product
abuse and may cause severe damage to the unit’s electrical
components.

Roof Fan Installation
Downblast Fans:
1.Position the fan with its wiring conduit in line
with the wiring coming up through the roof
curb and damper (if present). If the fan has
an external disconnect switch, position the
fan with the junction box towards the power
supply.
Upblast Fans:
1. Position the fan with its wiring conduit,
coming through the outer fan housing or its
external disconnect, towards the power
supply.
2. Run wires through the conduit to the switch.
Leave some slack in the wire in the motor
BEFORE START-UP: Disconnect power to this unit
before servicing the unit.
1. Check to verify that the wheel is free to
rotate.
2. For optimum fan performance make sure
that the wheel to inlet venturi overlap
(0.25”) is maintained.
3. Verify that supply voltage on the line side
of disconnect agrees with voltage on fan
nameplate and is within the 10% utilization
voltage.
4. Apply power to unit and check rotation of
wheel with the directional arrow on the unit.
WARNING: Rotation is critical. If
allowed to operate in the wrong
direction, the motor will overload and
bum out. Wheel rotation is clockwise
(CW) when viewed from the top
or drive side of the fan. Especially
check three-phase units for rotation.
For three-phase, rotation can be
changed by interchanging any two of
the three line leads. If unit is checked
on temporary wiring, it should
be rechecked when permanently
installed. Motor bum-out or tripped
overload protection devices are
usually the result of wrong rotation.
5. Electrical Input Check: Perform check of
fan ampere draw and verify that motor
nameplate amps are not exceeded. Take into
account the service factor range if the motor
is nameplated above a 1.0 service factor.
6. Fan RPM should be checked and veried with
a tachometer.
fantech
compartment so the motor and wheel
assembly can be lifted for inspection and
cleaning.
3. Bolt the fan base to the roof curb through
the holes provided on the base using eight
(8) lag bolts.
4. Make connection to the disconnect switch
per above electrical instructions.
5. Restaurant fan installation must be in
compliance with local codes and the
National Fire Protection Association’s NFPA-
96.
NOTE: The fan should not need
balancing, as it was balanced at
the factory to be within stringent
vibration levels before shipment.
However, there are several things
that may cause vibration, such as
rough handling in shipment and
installation, weak foundations and
alignments.
V-Belts
V-belts on these belt driven fans are oil, heat,
and static resistant type and oversized for
continuous duty. With proper installation and
maintenance, years of operating efciency can
be added to the lifespan of the V-belt drive.
The condition of V-belts and the amount of belt
tension should be checked prior to start-up
(see Figure1). When it becomes necessary
to adjust belt tension, do not over-tension as
bearing damage will occur. Recommended
belt tension should permit 1/64 deection per
inch of span of the belt at the center of the
belt span. To nd this point, measure halfway
between the pulley centerlines as shown in
Figure 2. Extreme care must be exercised when
adjusting V-belts as not to misalign the pulleys.
Any misalignment will cause a sharp reduction
in belt life and will also produce squeaky,
annoying noises (see Figure 3). On units
equipped with 2 groove pulleys, adjustments
must be made so that there is equal tension on
all belts (see Figure 4).
1. When tensioning loosen the motor mounting
bolts and slide motor until proper tension is
obtained.
2. Always loosen tension adjustment enough
to place belts on sheaves without running
Check, Test & Start Procedure
WARNING: Electric shock hazard.
Could cause severe injury or death.

belts over the edge of either sheave. A new
belt may be seriously damaged internally by
careless handling (see Figure 5).
WARNING: When removing or
installing belts, never force belts over
pulleys without loosening motor rst
to relieve belt tension. The fan has
been checked for mechanical noises
at the factory prior to shipment. If
mechanical noise should develop, then
some suggestions are offered here as
a guide toward remedying the cause.
1. Check rotating members for adequate
clearance.
2. Check proper belt tension and pulley
alignment.
3. Check installation and anchoring.
4. Check fan bearings.

Maintenance
Installation and maintenance are to be
performed only by qualied personnel who are
familiar with local codes and regulations and
experienced with this type of equipment.
CAUTION: Sharp edges and screws
are a potential injury hazard. Avoid
them.
WARNING: Hazardous moving parts.
Unit may contain protected fan motor
which may start automatically and
cause injury. Allow time for reset.
Disconnect power before servicing.
Preventive maintenance is the best way to
avoid unnecessary expense and inconvenience.
Start-up and routine maintenance should cover
the following items:
a. Tighten all setscrews, bolts and wire
connections.
b. Check belt tension and sheaves for wear.
c. Lubricate fan bearings (see Tables 1 and 2).
d. Cleaning of unit, wheel and damper (if
present).
All motors containing ball bearings
are permanently lubricated from the
factory. No additional maintenance is
required.
1. Before performing any maintenance on the
fan, be sure power is turned off and locked
in the OFF position at the service entrance.
2. Ventilators should be carefully checked at
least once a year. For critical or rugged
applications, a routine check every two or
three months is suggested.
3. All motors supplied with Fantech ventilators
carry a one-year limited warranty from date
of shipment. For repairs within the warranty
period, the motor must be taken to the
motor manufacturer’s authorized service
dealer. Contact your representative for
additional warranty details.
4. A periodic motor check should consist of
spinning the motor shaft with the power
off to be sure the motor turns freely and
the bearings run smoothly. The belt on belt
driven units should be removed from the
motor sheave.
5. When removing or installing a belt, do not
force the belt over the sheave. Loosen the
motor mount so that the belt can be easily
slipped over the sheave.
6. The belt on belt driven units should be
removed and carefully checked for glazing,
cracks, ply separation or irregular wear.
A small irregularity in the contact surface
of the belt will result in noisy operation. If
any of these defects are apparent, the belt
should be replaced. Check the sheaves also
for chipping, dents or rough surfaces which
could damage the belt.
7. The correct belt tension is important. Too
tight of a belt will result in excess bearing
pressure on the motor bearings and shaft
pillow blocks and may also overload the
motor. Too loose of a belt will result in
slippage which will quickly “burn” out belts.
A belt should feel “live” when thumped,
approximately W belt deection (3 to 5 lb.)
when subject to nger pressure at midpoint
between sheaves.
8. The belt alignment should also be checked to
be sure the belt is running perpendicularly to
the rotating shafts. Fan and motor
shafts must be parallel. Improper alignment
will result in excessive belt wear.
9. Check sheave setscrews to ensure
tightness. Proper keys must be in keyways.
10. Do not readjust fan RPM. If sheaves are
replaced, use only sheaves of identical size
and type.
11. If unit is to be left idle for an extended
period, it is recommended that belts be
removed and stored in a cool, dry place to
avoid premature belt failure.
12. The standard pillow block bearings on belt
driven ventilators are factory lubricated and
are provided with external grease ttings.
Lubrication annually is recommended, or
more frequently if needed (see Table 1).
It is recommended to add fresh grease at
start-up, but do not over-grease. Use only
1 or 2 shots of a recommended lubricant
with a hand gun in most cases (see Table 2).
Maximum hand gun rating 40 P.S.I. Rotate
bearings during lubrication where good
safety practice permits.
CAUTION: Greases of different soap
bases (lithium, sodium, etc.) may not
be compatible when mixed. Prevent
such intermixing by completely
purging the bearing of old greases.
The most frequent causes of bearing
failure are not greasing often enough,
using an excessive quantity of grease,
or using incompatible greases.
Excessive vibration, especially if
the bearing is not rotating, will also
cause bearings to fail. Bearings must
also be protected from water and
moisture to avoid internal corrosion.
13. During the rst few months of operation it
is recommended that the bearing setscrews
be checked periodically to ensure that they
are tight.
14. The rotating wheel requires particular
attention since materials in the air being
handled can build up on the blades to
cause destructive vibration or weaken the
structure of the wheel by corroding and/or
eroding the blade metal. Regular inspection
and corrective action at intervals determined
by the severity of each application are
essential to good service life and safety.
